I am wondering if I should buy a 106 or a 115, too. My weight is 75kg. I also have an Isonic 120 (2015) as a big board, so it is 80cm wide. I can use a 10m sail on that board, and 7,8 ans 8,5 of course. I mostly sail on flat spots like Podersdorf or Ringkobing Fjord, so Foil is no option for me. But the conditions often make me think of an wider board as a big board for those light wind days. A bigger falcon 140 or a Falcon lightwind might do the job, but here is the problem: I am definitely limited to a 2-board-strategy and I nevertheless want to participate at the German Windsurf Cup occasionally. So my question is, which combination of 2 Falcony might be the best if some day the Isonic breaks down.
But a 7,8 on a Falcon 140, is that a good idea? On the other hand, I know that usually a Slalom Competition at the GWC is started not before the wind is around 13 or 14 knots easily, so maybe a 115 could be the only "competition" board, powered with an 8,5, and the lightwind or the 140 could be my "easy going/early planing holiday" board.
On the other hand I am concerned about the upper limit of the 115. I clearly want to use a 6,4 sail on the new "small" board. That doesn't sound like the 115 would be the board. Therefore the 106 might be better, but then I definitely would need a bigger board to use in a competition as well (at the moment, of course, it would be the Isonic 120). That would kick out the Falcon lightwind. The 80cm Falcon might be perfect for competition, but I am no pro and I would like to use my 10m sail on lightwind days on a board which suits the sail better. So, the question is, I think: Falcon Lightwind + 115 or 140+106 or 140+115? Of course, at the moment the question is 106 or 115, but the answer is dependent from the whole strategy. Thank's for answering.
